Definitions

  • the electric hot plates have a hotplate body and a surrounding, made of sheet metal and projecting radially beyond the hotplate body, which rests with its radially inner part on the hotplate body, the The distance between the inner edge of an installation opening in an installation plate made of glass or ceramic material is covered and is supported on its outer circumference in the area surrounding the installation opening.
  • An elastic seal is interposed between the support ring and the mounting plate.
  • one embodiment provides for the seal to be inserted into a recess in the ceramic mounting plate and, in another embodiment, it is fixed by a rib surrounding the mounting opening.
  • the mounting plate is very strongly heated by the flange of the hotplate body projecting downwards.
  • the object of the invention is to provide a mounting arrangement which is particularly suitable for mounting plates made of glass or ceramic material and which reduces the mechanical and thermal stress on the mounting plate with a low installation height.
  • a mounting ring which is completely covered by the one-piece support ring, a substantially annular shielding section covering the inner edge of the installation opening and means for positioning the seal in such a position that its effective sealing area between the mounting plate and the support ring is close lies on the outer circumference of the support ring.
  • the effective sealing area is as far away from the hotplate as possible. It has been found that the heat conduction through the relatively thin-walled sheet metal support ring, in particular if it is made of stainless steel, is so low that the temperatures at the seal and mounting plate can be carried without additional intermediate rings which increase the height and the sealing problems would have to interpose.
  • the completely internal mounting ring shields both the inside edge of the mounting opening and thus the mounting plate itself and the seal from radiant heat. Due to the exact positioning of the seal, it is possible to work with a minimum of external holding force, i.e. the hotplate does not need to be clamped against the mounting plate with great force, which would put additional strain on it.
  • the precisely positioned seal which is held in place, also ensures that the hotplate cannot twist due to the static friction it applies. In this way, the hot plates stiffen the built-in plate instead of putting additional mechanical stress on it.
  • this On the outer circumference of the circular hotplate body 12, this has an upper, outwardly projecting flange 14 and a downwardly projecting, essentially cylindrical ring flange 15, the upper part of which is slightly tapered and forms a contact surface 16 for a support ring 17.
  • the radially inner part 18 of the thin, stainless steel support ring 17 rests on the contact surface 16 and on the shoulder 19 formed by the flange 14. He is fixed by a press fit, which is supported by the slightly conical shape of the contact surface 16. The lower inner edge of the support ring digs somewhat into the contact surface 16.
  • the central part 20 of the support ring 17 is inclined downward at a very flat angle of 5 to 20, preferably 10 °, and is relatively wide in comparison to the conventional support rings.
  • the width dimension projecting outwards over the flange 14 is, depending on the hotplate diameter, between 12 and 20 mm or between 7 and 10% of the diameter of the hotplate body.
  • the outer edge 21 of the support ring is inclined steeply downwards, but relatively narrow.
  • the electric hotplate 11 is built into a mounting plate 22 made of a relatively temperature-resistant glass, so-called block glass, which has an extremely low thermal expansion.
  • This built-in plate forms the upper plate of a stove or a built-in hob and has a plurality of installation openings 23 for hot plates.
  • the cut out of the flat mounting plate 22 are approximately 10 to 20% (preferably 15%) larger than the outer diameter of the contact surface 16 (nominal diameter of the hotplate), so that there is a relatively wide gap between the annular flange 15 and the edge 24 of the installation opening 23 forms. This is covered on its top by the support ring 17 and thus closed at the top.
  • the support ring 21 lies on the surface 25 of the mounting plate 22 in the region of the edge 24 of the mounting opening.
  • the glass mounting plate has the advantage of a very smooth, easy-to-clean and scratch-resistant surface, as well as freedom from distortion under thermal and mechanical stresses, which was not the case with mounting plates made of thin, stainless steel.
  • the installation opening 23 is surrounded by a sealing ring 26, which consists of a relatively temperature-resistant elastic material such as rubber or plastic, for example silicone rubber. It has a U-shape that surrounds the edge 24 of the installation opening.
  • the upper leg 27 of the sealing ring 26 lying on the surface 25 of the mounting plate 22 has, in the non-installed state, an upwardly directed bead 28 (shown in dashed lines) on which the support ring 17 rests in the area of its outer circumference, immediately adjacent to the outer edge 21, and it deformed in the form shown in the drawings.
  • the installation opening is therefore effectively sealed in this sealing area 29 against any food that may overflow.
  • the sealing ring 26 has two inwardly directed ring ribs 30, which hold an installation ring 31 at a distance from the central part of the sealing ring and thus the edge 24 of the installation opening.
  • the mounting ring 32 has an essentially L-shaped cross section and consists of very thin, stainless steel sheet with relatively low thermal conductivity. Its cylindrical shielding section 32 runs within the sealing ring 26 over the entire height of the sealing ring and thus the mounting plate and shields it from radiant heat from the hotplate body.
  • the upper L-leg forms an outwardly directed flange 33 which covers and shields the leg 27 of the sealing ring 26.
  • the mounting ring is hardly one Heat transfer from the electric hotplate exposed through conduction and provides good shielding against the radiant heat, for which purpose it is preferably made of bare, well reflecting sheet metal. He fixes the sealing ring both through the ribs 30 in the central area and especially through the end section 34 in the sealing area 29, so that the sealing area has a precisely defined and positioned position, which is supported on the surface 25 when the outer edge 21 of the support ring 17 is supported ensures a reliable seal.
  • FIGS. 2 and 3 correspond identically to the embodiment according to FIG. 1. These parts provided with the same reference symbols are therefore not described again. Similar or similarly acting parts have the same reference numbers with a different letter index.
  • the sealing ring 26 is positioned by a mounting ring 31a, which has no upward end portion 34, so that its obliquely downward flange 33a is enclosed on its outer edge by the material of the sealing ring when the bead 28 of the sealing ring is compressed.
  • This embodiment can be used advantageously if the material of the sealing ring is not too sensitive to cuts and the bead shape 28 ensures that the compressed material lies over the flange 33a in order to prevent the mounting ring 31a from moving upward.
  • an installation ring 31b is used, the flange 33b of which ends in a downward end section 34b which runs approximately parallel to the outer edge 21 of the support ring 17. This is due to the Inside of the support ring 17 within the sealing area 29 so that the sealing ring seals against the flange.
  • This embodiment can be advantageous if a precise dimensioning of the installation and support ring ensures that good sealing is also achieved in the sealing area 29 by metallic contact between the two rings and / or the seal also seals directly on the outer edge 21 at the same time.
  • the hotplate 11c differs from that used in FIGS. 1 to 3 in that the hotplate body instead of a projecting flange 14 has an upwardly tapering contact surface 16c on which the inner part 18c, which is conical in the same way, has one Support ring 17c is present.
  • the support ring 17c which is also fixed by being pressed on from below, snaps behind a projection 4o.
  • the middle part and the outer edge 20c, 21c of the support ring 17c are of a similar design as in FIGS. 1 to 3, as is the mounting plate 22.
  • a sealing ring 26c has a circular shape in the unloaded state and is fixed in the region of the outer circumference of the support ring 17c between the outer edge 21c and an upwardly directed end section 34c of a mounting ring 31c, the associated flange 33c of which rests on the surface 25 of the mounting plate.
  • the shielding section 32 also abuts the inner edge 24 of the mounting plate and engages with a lower flange 41 around the underside of the mounting plate.
  • the hotplate 11c is centered in the installation opening 23 of the installation plate 22 by means of spacers 41 punched out of the material and bent inwards.
  • Figure 5 differs in the shape of the mounting ring 31d, the shielding portion 32d of which is S-shaped in cross section, so that it contacts the inner part 18c of the support ring 17c on the one hand and there by spot welding can be attached and, on the other hand, rests at a point on the inner edge 24 of the mounting plate 22.
  • the hotplate is also centered in the installation opening in addition to the shielding.
  • This embodiment can be used if the mounting ring 31d has extremely low thermal conductivity properties, so that the heat conduction via the upper flange 33d does not play an important role.
  • the mounting ring 31e is again of an L-shaped cross section. However, its shielding section 32d runs at a distance from the inner edge 24 of the mounting plate 22, and this distance is maintained by a number of features 45 made on the circumference and directed towards the edge 24.
  • the upper flange 33c with the end section 34c projecting obliquely upwards corresponds to the embodiment according to FIG. 4.
  • FIG. 7 also corresponds to the designs according to FIGS. 4 to 6 with regard to the hotplate, support ring and mounting plate, but the support ring on its conical contact surface 16f is additionally secured against "creeping" upwards by a small outward projection 46, which may be the case due to different thermal expansions could occur if the cone angle of the contact surface 16f is chosen to be lower. It should be avoided at all costs that the support ring 17c moves higher than the cooking surface 13 due to such creep, because then the Cooking vessels would stand on the support ring and heat contact with the cooking surface would be lost.
  • the mounting ring 31f is, as can be seen in particular from FIG. 8, wave-shaped or star-shaped, so that the upper flange 33f consists of individual triangular sections, the tips of which are bent up and thus form the end sections 34f positioning the sealing ring 26c.
  • the shielding section 32f is also deformed in a star or wave shape, the outer apexes in each case guiding the sealing ring on the inner edge 24, while the inner apexes 47 can interact with the hotplate body for positioning.
  • an air space is formed between the shielding section and the inner edge 24, which additionally contributes to the insulation.
  • the gap between the hotplate and the inner edge 24 of the mounting plate is drawn relatively small, but in practice it can have the same dimensions as shown in Figures 1 to 3.
  • the support ring design and arrangement on the hotplate body according to FIGS. 4 to 7 has the advantage of an even flatter installation of the hotplate over the surface 25 of the mounting plate.
